Abstract: The present invention relates to an optical deflector driven by an electrical signal, and a wavelength tunable external resonator using the same. The optical deflector of a triangle shape, capable of controlling the refractive index of a beam depending on the electrical signal, is positioned between a reflection mirror and a diffraction grating in a Littman-Metcalf mode external resonator or between a lens and the diffraction grating in a Littrow mode external resonator. Thus, even with the reflection mirror and the diffracting grating fixed, the refractive index of the beam generated from a laser diode can be controlled by adjusting the electrical signal applied to the optical deflector, so that beam having a specific wavelength can be focused and the wavelength can be rapidly and consecutively tuned.

Abstract: Disclosed herein are ammonia-specific 5′-XMP aminase mutants and a method for preparing the same. A mutation is introduced into the active site of glutamine-dependent catalysis in 5′-XMP aminase. The resulting 5′-XMP aminase mutant is devoid of the glutamine-dependent activity and specifically reacts with external ammonia in converting 5′-XMP into 5′-GMP. Thus, the ammonia-specific 5′-XMP aminase mutant is stabler within cells compared to the wild type, and can be useful in the industrial conversion of 5′-XMP into 5′-GMP.
